Circular metabolism

Human society and culture are preserved. Energy is intelligently preserved waste is avoidedand cascaded when lower values of energy are available for use e.

No single strategy can achieve zero waste. And in fact we know that simply choosing for renewable materials does not always result in less environmental impact or greater value delivery — nor does adopting a leasing scheme. To achieve this, the efficiency of our energy use also needs to increase significantly.

Moreover, a quantitative method, Ecological Network Analysis, is incorporated into MAS knowledge to analyze and establish relationships and metabolic pathways between companies, which can increase the circularity of technical nutrients and reduce biological nutrient extraction.

Circular metabolism: turning regenerative cities into reality

In contrast, the Circular metabolism of Circular metabolism modern cities is essentially linear, with resources flowing through the urban system without much concern about their origin or the destination of wastes. To be able to apply this concept to urban design and planning, one has to understand the different flows Circular metabolism the different scales of the city and its hinterland Circular metabolism well as the corresponding infrastructures.

Whenever we recommend a course of action as part of a circular strategy, we make sure to evaluate whether or not our proposed solution for Circular metabolism area of impact will not be causing a problem or externality in one of the other target areas of performance.

Oakland shows that solutions and best policy examples exist, so there is no time to lose in developing strategies to support their implementation elsewhere.

It is us, as citizens, that we need to manage these processes in a sensitive, informed way, playing a key role to the overall function of our city.

Girardet characterizes this as a natural world process. By tracing flows of energy, materials and waste through urban systems as a whole, changes and alterations can be made to close the loops to create circular metabolisms where resources are recycled and almost no waste is produced.

As Herbert Girardet says, in order for cities to become more sustainable they must change the linear to a more circular metabolism, creating a self-regulating sustainable relationship with the biosphere. Materials are incorporated into the economy in such a way that they can be cycled at continuous high value.

Vertical support is important not only to enable local authorities, but also to support horizontal coordination around a common goal. More recently the metabolism frame of reference has been used in the reporting of environmental information in Australia where researchers such as Newman have begun to link urban metabolic measures to and it has been suggested that it can be used to define the sustainability of a city within the ecosystems capacity that can support it.

The relevant types of physical infrastructure present in the Netherlands which are considered in regard to the concept of Urban Metabolism, are as follows: Here again, processes in nature where cycles are closed and waste from one process is input for another, are models for the urban situation.

Oakland shows that solutions and best policy examples exist, so there is no time to lose in developing strategies to support their implementation elsewhere. This was possible by explicitly returing discarded materials to the local economy, applying the waste management hierarchy in priority order reduce, reuse, recycle, and compost to the maximum extent, and promoting recycling market development.

Many groups define the circular economy in terms of the types of activities and concepts associated with it: In Marchthe Oakland City Council adopted the goal of zero waste by Biodiversity is structurally supported and enhanced through all human activities.

Furthermore, each one can be characterized in greater, quantitative detail, forming the basis for Circularity Indicators, or KPIs, in many different contexts. Antonia Kalatha Urban metabolism - from linear to circular Have you ever wonder how do the flows of goods, waste, energy, people, water and air function in your city?

The city of Oakland reduced its annual tonnage to landfill fromtonstonnes totonstonnes in only four years. On this basis, we have developed a set of circularity factors that provide guidelines for the optimal use of materials for different functions.

Beyond Materials But of course, in doing this exercise, we also immediately realized that once you are developing goals for how materials should ideally be managed, you also run into many adjacent issues.

Vertical support is important not only to enable local authorities, but also to support horizontal coordination around a common goal.

The Seven Pillars of the Circular Economy

On a predominantly urban planet, cities will need to adopt circular Circular metabolism systems to assure their own long-term viability as well as that of the rural environments on which they depend. Greenhouse gas accounting[ edit ] Staying in line with the notion of sustainability, urban metabolism is also a helpful tool for tracking greenhouse gas emissions on a city or regional level.

It was corrected on the 13th of November The materials required for energy generation and storage technologies are designed for recovery into the system. The length of materials cycles is matched to material scarcity: Even though we know the total amount of energy available on the planet is not a constraint the sun produces more than enough for everything we needcollecting that energy in usable form does require the use of scarce materials, which are a constraint themselves.

They also used metabolism to describe the material and energy exchange between nature and society in as a critique of industrialization which created an interdependent set of societal needs brought into play through the concrete organization of human labour.The circular metabolism is characterized by the reduced amount of resource inputs, less waste generations as outputs, and the efficient use of resources in a system.
